What if the hostility is due to jealousy? They might be trying to troll each other, so you can become exclusive with them, as they may believe they're the more level headed of the two.

I'd considered that but it's more like they're just incapable of understanding each other on an emotional level. I'm completely outside of the dispute, and neither one has a problem with me or anything that I'm doing. The relationship between the three of us is unbalanced because even though we're all friends, the two of them don't know each other as well as I know each of them, it sort of comes down to a trust thing, they each trust me, and I trust them, but thwy don't fully trust each other because there's a lack of familiarity. Idk.
